While some kinds of workouts require consistent heart rate data in order to track calorie burn rates more accurately, it isn't necessary for all kinds of workouts. That's why the Apple Watch gives you a way to disable consistent heart rate tracking during certain kinds of activities. In turn, you get a little more battery life out of your Apple Watch. Here's how!
By performing the steps below, your Apple Watch will not consistently monitor your heart rate during walking and running workouts. It will continue to monitor heart rate on a constant basis during any other kind of workout. And if you ever decide you want more frequent heart rate data during a specific run or walk, you can always re-enable the setting on the fly whenever you'd like.
How to conserve on Apple Watch battery life during workouts
- Launch the Apple Watch app on your iPhone.
- Tap on Workout.
- Tap the *Power Saving Mode switch**. Green means power saving mode is turned on.
You can also save your battery life by using accessories: An external Bluetooth heart rate monitor (opens in new tab) will save the watch from having to take heart rate readings during exercise, as will bringing your iPhone with you on walks or runs if you have a Series 2 Apple Watch (so as to avoid active GPS use).

So if i disable this this there is no way of accurately knowing what my calorie count is then. But i can get my heart rate on demand by using glances and swip til u see the heart.
So in order to get through the day with my battery, I should opt for a less accurate activity measurement. Of course, one reason I bought the Watch is for fitness monitoring. Grrrr Sent from the iMore App
I have absolutely no problems in getting through the day with the battery of my Apple Watch. I can barely hit 20% by night in a very intensive day (usually it's 30/40%)
When I go to the setting on my phone it sounds like heart rate sensing is completely disabled for running and walking workouts. The article makes it sound like it is not disabled but just reduced.
Non sense in my opinion. I need those data
Yes this is dumb. Of you want a watch go buy a watch. If you want a fitness tracker use it for what it's meant for and charge it when you are done. I didn't pay over $500 for a watch I'm only going to get 1/2 use out of. Sent from the iMore App
